The difficulty of hiding plants seems to be about the only obstacle to growing them, since pot is becoming legal, we can assume that growing it will become legal or decriminalized at some point.
Since you seem to know, tell me the statistics on how much pot growing was taking place in Colorado before the drug was legalized, and how much is being grown now.
"Possessing, growing, processing, or transporting no more than six marijuana plants, with three or fewer being mature, flowering plants, and possession of the marijuana produced by the plants on the premises where the plants were grown, provided that the growing takes place in an enclosed, locked space, is not conducted openly or publicly, and is not made available for sale."
